Base-Ethereum Account Abstraction Effort Broke Down, Developer Says

The split matters less as a technical disagreement than as a signal about who absorbs the cost of divergence. If Base and Ethereum ship incompatible native smart accounts, the burden of keeping accounts portable falls on wallets and applications, which typically means slower, uneven support rather than a clean failure. The open question is whether the two drafts converge later or harden into separate standards, since that determines whether account portability becomes a shared baseline or a per-chain feature.
